27.4 Menus (cont.)

• Each menu item must have an integer ID number, used to match up menu items with their actions.

  const int ID_SAY_HELLO = 1000;
  const int ID_SAY_GOODBYE = 1001;

• Now construct a menu and append the two menu items to it.

  wxMenu* menu = new wxMenu();
  menu->Append(ID_SAY_HELLO, "Hello");
  menu->Append(ID_SAY_GOODBYE, "Goodbye");

• Finally, constructor a menu bar object, set it as the menu bar of the frame, and append the menu.

  wxMenuBar* menu_bar = new wxMenuBar();
  SetMenuBar(menu_bar);
  menu_bar->Append(menu, "Say);
